Los ensayos de Joaquín de Villalba (1752-1807) sobre la vacuna de la viruela en la Escuela de Veterinaria de Madrid

La rápida propagación del método empírico para combatir la viruela dado a conocer por Edward Jenner conllevó algunas dificultades. A la necesidad de obtener la máxima aceptación posible entre la población, se añadió la de ejecutar con rigor la técnica así como la de producir, transportar y conservar el fluido vacunal con garantías de calidad. Abastecerse de vacuna era una preocupación solventada en parte gracias a los envíos realizados desde instituciones radicadas en Londres o París. Tras su recepción se iniciaban cadenas de vacunaciones mediante la técnica del brazo a brazo. El temor a la extinción del fluido vacunal, no obstante, despertó el interés por la producción autóctona. Era necesario encontrar vacas afectadas por viruela vacuna o en su defecto aprender a conservar la materia vacunal en las propias vacas u otros animales. Varias iniciativas exploraron esta posibilidad. El fondo documental de la Biblioteca Nacional de España conserva un texto que refleja 2 de estos ensayos realizados en la Real Escuela Veterinaria de Madrid a cargo del médico Joaquín de Villalba y el albéitar Antonio Roura en 1802 y 1803. La tentativa no obtuvo el éxito deseado.
